ORBI Satellite RBS50 not connecting (and top LED not lighting)

Thanks so much for your response. 

I have already checked on the Orbi web app as well as the smart phone app which both list no satellites connected.  Those apps do list all the other devices (ipads, echos, phones) that are all attached to the router.

I am aware that the LED is not lit when the router and satellite are working normally, but is should turn on temporarily when it is restarted and syncing, right?  When I unplug the satellite then plug back in, the green power light comes on, but the LED does not at all.  It is my understanding that the LED light should turn solid white (mine does not), then when I push the sync button it should pulse white (mine does not) before turning blue for a few minutes after it successfully connects (p141). 

Does this mean the LED light is broken? if so I would think I should still be able to sync it, I just wouldn't get the visual feedback that is was looking then successfully connected (3 minutes of the blue LED light)

Does this mean I need to reboot or reset the satellite?  I tried that, but perhaps I have to do it in some specific sequence?

Does this mean the satellite is no longer functional?  That would be a shame, since I bought it 14 months ago and the warranty lasts 12 months. 

Any advice guidance you have is greatly appreciated!
